UNITED STATES PATENT OEEIcE.

A. Gr. SHAVER, OF NEV HAVEN, CONNECTICUT.

COMBINED ERASER AND BURNISHER.

Specification forming part of Letters Patent No. 49,559, dated August 22, 1865.

To all whom it may concern:

Be it known that I, A. G. SHAVER, ofNew Haven, in thc county of New Haven and State of Connecticut, have invented a new and usei'ul Improvement in Erasers and Burnishers; and I do hereby declare the following` to be a full, clear, and exact description of the same, reference bein g had to the accompanying drawings, in which- Figures 1, 2, and 3 show different methods Ot' constructing my improvement.

rlhe nature ot' my invention consists in constructing.;` erasers with polished steel, agate, or other mineral or metallic burnishers, attached to aconvenient or desirable partot the implement, substantially in accordance with the following description.

In an instrument designed and adapted for the erasure ot ink from paper or parchment it is well 1Known that a suitable burnisher is as necessary as a proper' blade, and it is also well known that a suitable and efficient burnisher can only be formed ot' a material susceptible ot' receivinga very high polish and possessing,` great hardness, as steel or some ot' the minerals. Itherefore construct burnishers in the form ofbosses or buttons, as shown in the figures, and attach them to the shank of the eraser, as shown at a, Fig. 2, to the shoulder ofthe handle, as at b, Fig. 3, or to the end ot' the handle, as at c, Fig. l. In form the bos\` maybe circular, oval, or of any other shape, and very convex on the surface, so that when used in burnishing, the prominence of the surface of the burnisher will be sufticient to insure its convenient use without endangering the sur'- face of the paper or parchment by cutting` with the point or edge of the eraser. This point is fully illustrated in Fig. 3.

The above-described bosses may be attached in any suitable way by tangs, rivets, screws, or otherwise, as may be preferred. When they are applied, as in Fig. 3, to the shoulders ot' the handle cfa desk-knife with a movable blade 'they take the place of the conmon holsters,

which are not adapted or designed for any such purpose and cannot be used for any such purpose with ease and facility.

Havingdescribed my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

In combination with the blade or handle of an eraser or desk-knife, the metallic or mineral boss, button, or bolster hurnisher, substantially as described.
